Perhaps this is a dumb question. when I first purchased the Citation II SP some years ago the installers' title was Cessna Citation IISP; Then an update was introduced and that installer was C II / SP 1.5.

Then I got C IISPX.exe and it shows in the aircraft.cfg file as:Eaglesoft CitationII1.5

I have the key carefuly put away and the corrected air.cfg with the corrected Left hand side window showing the window frame just want to know if I am missing anything and what is the difference between the two files and if there is a difference can I simply run the new installer ( CIISPX.exe)
